Abstract

Abstract: Boron nitride nanosheets (BNNS) were first time successfully exfoliated from hexagonal boron nitride (h‐BN) in an ethanol‐sodium hydroxide media using a microwave irradiation method. This simple and low‐cost exfoliation method enabled the fast produce of high quality BNNS within 2 min. The average sheet thickness and lateral size of BNNS were 4.34 nm and 1.13 μm, respectively. The exfoliated BNNS bear a strong negative charge and was demonstrated to be an excellent platform for depositing high density nanoparticles after proper surface modification. As an example, unique core‐shell nanostructure of BNNS/dense palladium nanoparticles was synthesized and its electrochemical catalytic behaviour towards the oxidation of paracetamol was studied in detail. Abstract : A facile method for the rapid exfoliation of Boron Nitride Nanosheets (BNNS) from hexagonal boron nitride was proposed using microwave irradiation combined with an ethanol‐sodium hydroxide system. The exfoliated BNNS bear strong negative charges and was demonstrated to be an excellent platform for the preparation of unique BNNS/Pd core‐shell nanostructures which exhibited outstanding electrocatalytic activity towards the oxidation of paracetamol.
